Description

Technical Field

[0001] The invention belongs to the technical field of dough mixer applications, and in particular relates to an open-and-close continuous vacuum dough mixer. Background Art

[0002] Dough mixers, used in dough processing equipment, typically operate under atmospheric pressure and ambient conditions. During the kneading process, tiny bubbles cling to the flour's surface, preventing it from quickly and fully absorbing moisture. Even during mixing, this process struggles to achieve optimal absorption, resulting in a poor gluten network and high stickiness in the dough, resulting in poor-tasting noodles.

[0003] To address these common issues with dough mixers, vacuum dough mixers have emerged. The key feature of these mixers is that the dough mixing process takes place under vacuum. The flour and water are mixed in a vacuum, allowing the water to be fully absorbed by the flour. This significantly improves the gluten network in the dough, resulting in a superior noodle texture.

[0004] However, a common problem with existing vacuum dough mixers is that the vacuum kneading process is intermittent. During each vacuum kneading cycle, the kneading chamber must be manually opened, filled with water, and then the vacuum chamber must be closed to knead the dough. After the dough is kneaded, the chamber must be opened again to remove the dough. This operation is not very effective for the production of steamed buns and other products in a typical workshop. However, it poses a significant problem for factory-based production. The frequent removal and placement not only increases labor intensity but also reduces efficiency, making it impossible to effectively form a streamlined production system.

[0005] To this end, people have designed a continuous vacuum noodle mixer. The continuous vacuum noodle mixer uses a noodle pipe and a water pipe set at one end of the noodle container to realize the automatic input of noodles and water, and uses a discharging device to realize the output of dough, effectively realizing streamlined input. However, cleaning the vacuum noodle mixer after use has always been a problem that troubles users. This is because the cavity of the vacuum noodle mixer must remain sealed, so its shape is designed to be more rigorous and the size of the cavity cover is limited. It is inconvenient for the operator to use the cleaning tool to explore every corner inside the cavity, which may lead to the problem of unclean cleaning in the cavity of the noodle container. Summary of the Invention

[0006] Aiming at the technical problems existing in continuous vacuum dough mixers, the present invention proposes an open-and-close continuous vacuum dough mixer which has reasonable design, simple structure, convenient processing and easy cleaning.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows: The present invention provides an opening and closing type continuous vacuum dough mixer, which includes a frame and a dough container arranged on the frame.

Detailed implementation manners

[0024] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0025] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0026] Embodiment 1, as [[ID=X]] Figures 1 to 5 shown, the purpose of this embodiment is to provide a continuous vacuum dough mixer that is convenient to clean to ensure the cleanliness and hygiene of the dough mixer. To this end, the openable continuous vacuum dough mixer provided in this embodiment includes a frame 1 and a dough container provided on the frame 1. A dough conveying pipe 4 and a water conveying pipe 5 are provided at one end of the dough container, and a discharging device 7 is provided at the other end. A vacuum pipe 6 is provided on the top of the dough container. The vacuum pipe 6 needs to be provided close to the discharging device 7 to ensure that no flour is adsorbed. A dough kneading cavity is provided in the dough container. The dough conveying pipe 4, the water conveying pipe 5, the vacuum pipe 6 and the discharging device 7 are all communicated with the dough kneading cavity. In this embodiment, the discharging device 7 is a roller-type discharging device 7.

[0027] The above structure is a common existing structure, so it will not be described in detail in this embodiment. Considering that the main reason for the inconvenient cleaning of the dough container of the continuous vacuum dough mixer is that the dough container is sealed and the length of the dough container is relatively long, and the human arm cannot cover the entire dough container, resulting in dead corners that cannot be cleaned in the dough container. To this end, in order to solve the problem of dead corners, in this embodiment, the dough container includes a left container 2 and a right container 3 arranged left and right. The left and right arrangement in this embodiment is to divide the dough container from the middle along its short side direction. Such a design can ensure the coverage range of the arm and thus facilitate cleaning.

[0028] Since it is divided into two equal parts, a left kneading cavity 21 is provided on the left container 2, and a right kneading cavity 31 is provided on the right container 3. The left kneading cavity 21 and the right kneading cavity are symmetrically arranged, and the left kneading cavity 21 and the right kneading cavity form a complete kneading cavity.

[0029] To separate and close the left kneading cavity 21 and the right kneading cavity, a slideway 12 is provided on the frame 1. Sliders that cooperate with the slideway 12 are provided at the bottoms of both the left container 2 and the right container 3. Sliding cylinders 11 are provided on the backs of both the left container 2 and the right container 3. The fixed ends of the sliding cylinders 11 are provided on the frame 1, and the power ends of the sliding cylinders 11 are fixed to the backs of the left container 2 and the right container 3. In this embodiment, four sliding cylinders 11 are provided on each side to ensure the stability of sliding. In this way, the left container and the right container 3 move towards or away from each other under the action of the sliding cylinders 11, achieving the opening or closing of the kneading cavity. When it is closed, continuous kneading is achieved. When it is opened, since the short side is divided into two equal parts, it is convenient for cleaning.

[0030] Of course, when it is closed, its sealing performance needs to be ensured. For this purpose, in this embodiment, a sealing protrusion 32 is provided on the right container 3. The cross-section of the sealing protrusion 32 is square, and the sealing protrusion 32 is arranged along the contour of the right kneading cavity. That is, the shape of the opening of the right kneading cavity on the left container 2 is rectangular, so the sealing protrusion 32 also forms a rectangular shape. Of course, at the same time, a sealing groove 22 that cooperates with the sealing protrusion 32 needs to be provided on the left container 2. In this way, the sealing protrusion 32 is inserted into the sealing groove 22 to achieve sealing, thereby ensuring the vacuum effect.

[0031] To further improve the vacuum effect, in this embodiment, a sealing gasket is provided on the side wall of the sealing groove 22. The sealing gasket is a rubber gasket or other plastic soft gasket. By adding the sealing gasket, the sealing effect is further ensured, providing the necessary conditions for the vacuum.

[0032] Considering that relying solely on the pushing of the sliding oil cylinder 11 can achieve a sealing effect, but it may not be very thorough. Therefore, in this embodiment, a locking rod 33 is further provided on the right container 3. The locking rod 33 is a cylindrical rod, and the locking rods 33 are arranged at intervals along the contour of the right cavity. The locking rod 33 is arranged close to the sealing protrusion 32 and is located above the sealing protrusion 32. At the same time, a locking hole 23 matching the locking rod 33 is provided on the left container 2. The locking rod 33 penetrates through the left container 2. A locking cylinder 24 is arranged on the back of the left container 2. The power end of the locking cylinder 24 is connected with a locking fork 25 arranged in a U shape. An annular notch 331 matching the locking fork 25 is provided on the locking rod 33. The top surface of the locking fork 25 is arranged as an inclined surface. In this way, as the locking fork 25 penetrates deeper, its inclined surface tightens the locking rod 33, forming a sealing structure similar to that of a bolt-fixed flange, thereby ensuring the sealing effect. And the control of the locking cylinder 24 facilitates detachment. In this way, the sealing leakages possibly caused by the slight changes of the sliding oil cylinder 11 are solved.

[0033] Considering that the dough mixer mainly imitates the pressing of flour by humans during the dough kneading process to form a gluten network, ultimately achieving the best state of the dough's toughness and chewiness. In a traditional vacuum dough mixer, since the dough does not move in the chamber, under the contact and extrusion of the stirring device and the dough chamber, a good extrusion effect can be achieved, thus ensuring its toughness and chewiness. However, in a continuous dough mixer, there is dough movement. If a traditional cylindrical chamber is used in combination with a rod-shaped stirring structure, it is very difficult to achieve the same effect as the discontinuous type. Therefore, to achieve the same effect, in this embodiment, the left dough chamber 21 and the right dough chamber are sequentially provided with a first dough chamber 311, a second dough chamber 312, a third dough chamber 313, a fourth dough chamber 314, and a fifth dough chamber 315 from the dough conveying pipe 4 towards the discharging device 7. Among them, the cross-sections of the first dough chamber 311 and the fifth dough chamber 315 are both circular, and the second dough chamber 312, the third dough chamber 313, and the fourth dough chamber 314 are all elliptical. The first dough chamber 311 and the fifth dough chamber 315 are set like this mainly considering that during the process of raw material entry, mainly flour and water, in this chamber, it mainly completes a mixing process and does not require excessive extrusion, mainly for the convenience of mixing. The fifth dough chamber 315 is for extrusion, and the dough stays in the fifth dough chamber 315 for the shortest time. Therefore, the cross-sections of these two chambers are circular. The second dough chamber 312, the third dough chamber 313, and the fourth dough chamber 314 are the chambers mainly for kneading and pressing. At the same time, considering that in a continuous vacuum dough mixer, the movement of the dough in front is driven by the dough behind. In this case, due to the stirring mechanism being unable to approach the end in the horizontal direction in the elliptical dough chamber, after a certain amount of dough accumulates in the elliptical dough chamber, the stirring structure can only contact the dough. In this process, the dough directly contacted is a large dough, which not only undergoes a certain amount of kneading and pressing during the accumulation process, but also has a large amount of dough for kneading and pressing after contact, thus being able to provide a better kneading and pressing effect and achieving a better kneading and pressing effect.

[0034] To further improve the kneading and pressing effect, in this embodiment, stirring shafts 8 are provided in the first dough chamber 311, the second dough chamber 312, the third dough chamber 313, the fourth dough chamber 314, and the fifth dough chamber 315. Each stirring shaft 8 corresponds to a stirring motor. Among them, stirring rods 81 are provided on the stirring shaft 8 in the first dough chamber 311. The stirring rods 81 are evenly distributed on the stirring shaft 8. The stirring rods 81 are cylindrical rods, and a total of 3 groups are provided, with four stirring rods 81 in each group. This is the form of the existing common stirring mechanism, so in this embodiment, no detailed description will be given.

[0035] Considering the characteristics of the oval dough mixing cavity, accordingly, in order to match its shape, in this embodiment, auxiliary stirring rods 82 are provided on the stirring shafts 8 of the second dough mixing cavity 312, the third dough mixing cavity 313, and the fourth dough mixing cavity 314. Pressure plates 821 are provided on the auxiliary stirring rods 82. In this embodiment, the pressure plate 821 is similar to the structure of a tire, and it is bent up and down and left and right. The purpose of this setting is to provide an extrusion surface. At the same time, the pressure plates 821 on adjacent auxiliary stirring rods 82 are also staggered to ensure the pressing effect. In addition, in this embodiment, 4 groups of auxiliary stirring rods 82 are provided. In this way, the gap between groups is smaller, and a better pressing effect can be provided.

[0036] In order to delay the time in the fifth dough mixing cavity 315, an extrusion cylinder 83 is sleeved on the stirring shaft 8 of the fifth dough mixing cavity 315. The extrusion cylinder 83 has two purposes. The first purpose is to further reduce the gap between the cylinder wall and the cavity wall and perform the last kneading and pressing. The second purpose is that when the discharging device 7 is not working, since the extrusion cylinder 83 has a cylindrical surface, the dough will adhere to the extrusion cylinder 83, and the centrifugal force is not so large, so it will stay for a longer time. And as long as it adheres, when the discharging device 7 is turned on again, it is also necessary for the cavity to be full before the dough can be discharged one after another, so as to ensure the kneading and pressing effect.

[0037] In order to better reflect the kneading and pressing effect, annular protrusions 831 are provided on the extrusion cylinder 83. The annular protrusions 831 are arranged at intervals on the extrusion cylinder 83. In this way, an interleaved kneading and pressing is formed to improve the kneading and pressing effect.

[0038] Through the above settings, it is effectively realized to facilitate cleaning while improving the dough mixing effect.

[0039] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in this field may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
